ConnectSafe: Browsers won't work

Hello- recently started using ConnectSafe and really like it.  I am having one issue however and it is rather random.  I have a PC which is running Windows 8.1 and there are times when I cannot load any webpage from any broswer.  A restart of the machine fixes it.  I am connected to the internet when this happens as i have a non browser application that works just fine when this occurs.  I am using Windows Explorer and Chrome.  All current versions.  Thanks.
